WATEBrCLOSET.

Specification of Letters Patent.

Patented Dec. 1, 1914.

To all whom it may concern:

Be it known that I, FRANK WEINRICH, a citizen of the United States, anda resident of the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Water-Closets; and I do hereby declare that the following description of mysaid invention, taken in connection with the accompanying sheets ofdrawings, forms a full, clear, and exact specification, which willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates generally to improvements in a water closet, andit consists, essentially, in the novel and peculiar combination of partsand details of construction, as hereinafter first fully set forth anddescribed and then pointed out in the claims.

In the drawings already referred to, which serve to illustrate my saidinvention more fully, Figure 1 is a longitudinal, vertical section of awater closet bowl, in which my invention is incorporated. Fig. 2 is alike section of a fragment of said bowl on an enlarged scale. Fig. 3 isa plan of my invention. Fig. 4 is a vertical section in the direction ofthe arrow pointers in line 4-4 of Fig. 1. Fig. 5 is a vertical sectionof a detail of construction.

Like parts are indicated by corresponding symbols or characters ofreference in all the figures of the drawings.

In many municipalities ordinances have been enacted providing that theseats proper on water closet bowls in public places must be maintainedin a position considerably away from contact with the bowls when not,

in use, so that a free circulation of air between the top of the bowland bottom face of the seat may take place.

One of the objects of my invention, there fore, is the production of acounterbalanced seat of new and novel construction, whereby the seat maybe maintained at any predetermined distance from the bowl when not inuse, there being incorporated therewith adjustable devices whereby theheight of the seat from the bowl may be varied.

Another object of my invention is the provision of hinging devices forthe seat which have no contact with nor fastening to the exterior of thebowl whatever, so that 001'- rosion of these elementsis prevented.

Still another object of my invention is the r f incorporation of meansin connection with the hinging devices, so coacting, that when a personarises from the seat, the latter will swing up to a higher point thanits normal position, and cause to be actuated, through suitable media,the outlet of a flushing tank for the closet how].

To attain these results I now refer to the drawings in which- Adesignates a water closet bowl of a general type of construction,usually made from porcelain, and Bthe siphon outlet therefor. (l is theupper rim of said bowl, and D an annular water passage therein, therebeing a plurality of downwardly extending openings 'F, whereby flushingwater passin through said passage D may enter said bowl and flush thesame.

Directly behind the bowl A proper and located above the siphon outlet Bthere is an essentially rectangular chamber E formed by the top wall ofthe siphon outlet, the back wall of the bowl proper, and by side walls 1and 2, a rear wall 3, and a top wall t, the latter being of the sameheight as the top face of the bowl rim C. In the said top wall is formeda water passage 5 communieating with the passage D in the bowl rim C.Water from a typical flush tank having a typical flush valve is conveyedto water pas- .Takge 5 through an upright flush pipe 6 or the The flushtank and valve above mentioned may be of any of the many types on themarket and for that reason are not shown in the drawings.

It is to be understood that the bowl proper, the siphon outlet walls,and the walls for the chamber E are integrally formed by the usualprocesses of pottery work for this class of goods.

Piercing the top wall 4 of chamber E, on either side of the waterpassage 5 and communicating with chamber E are circular openings 10 and10'. A short distance to the rear of these openings and in alinementtherewith, there are two other openlugs for the rece tion of eye bolts11 and 11, the heads 0 which bolts are located within chamber E as seenin Fig. 2; nuts 12 and 12" being employed to rigidly maintain said boltsin position; Pivoted to and depending from said bolts are hinge memhersL, each comprising depending legs 13 and 13* and a connecting bar 14:.At the lower ends of these legs are located bosses with set screws 16and 16, and sai' arcuate openings therein are provided for the receptionand passage t erethrough oi arouate rods 17 and 17. These rods are bentto a semicircle to a radius having its center in the pivotal centers ofthe hinge members IA, it heing now understood that the openings 10 and10 through the top 4 are pro-- duced on a like radius and adapted forthe free passage therethrough of one end of each of the rods 17 and 17,which said ends are firmly embedded in a suitable closet seat S. lheopposite ends of said rods terminate in a nose 18 for purposeshereinafterdescribed, and on said rods loetween leg 13 and nose 18' areslidahle counterwoights 19 (one on each rod) which are held in anydesired position on said rods by set screws 20.

lit will now be observed that by a proper positioning of thecounterweights 19 on the rods 3.? and 17 any desired normal angularitybetween the bottom face of the seat S and the top face C of the rim-ofthe loowl'A, may he estalolished while the seat is at rest. And, it willhe understood that when the seat is depressed to the rim or": the bowl,as when a person is seated thereon, the counter weights have shifted toa position in which they will impart a much greater upward force to saidseat when a person arises therefrom, and cause said seat to swing to amuch higher position than normal, otter which the same will oscillateuntil itcomes to rest at the normal angularity.

Adjacent the flush pipe 6 hereinhefore reterred to, there is a smallupwardly entending tuhe 21 which reaches to within a short distance ofthe valve handle of a tank flushing valve (not shown). The said tube hasits lower end in contact with top 4, and is in alinement with an opening"22 passing through said top. Axially helow opening 22 and tired to theunderside of the top 1- is located a short, open ended, tube 23, havinga longitudinal slot 24 at the upper end thereof. Adapted to freely slidewithin this tuloe is located small cylindrical weight 25 to which isattached a light wire 26, the upper end. oi which is fastened to theflush tank valve (not shown) alreadyreit'erred to.

Said weight 25 is of sufiicient weight only 7 to maintain a very slighttension in wire 26; enough only to tauten said wire, in fact. The 25 hasa nose 2? projecting through. slot 24 of tube which nose at its outerextremity apivoted dog 28. 'lhe nose 18 of the arcuate hinge rods It?arrears and 17 is ada ted to engage said dog, which is so arrange" as tobe rigid with said projection 27, when downward pressure is applied,while. upon application of upward "force the dog will yield thereto;

The operation of the flushing elements of my invention may now bedescribed as follows, it; being assumed that flush pipe 6 andflush-valve wire 26 are properly connected to a suitable flush tank andits valve, respectively: By reference to Fig. 2 it will be seen thatseat S is in its normal position while at 1 rest with the nose 18practically in contact with the-upper face of dog 28. When the seat. isdepressed, as under the weight of a person seated thereon, the nose l8swings upwardly and away from said dog, while counter-Weights 19 assumea position toexert a greater upward force upon the seat when the weightis removed therefrom, which will cause said seat to swing intoapproximately the position shown in Fig. 1. When the seat swings up, thenose strikes the dog 28, and forces it, together with the weight 25 andwire 26 downwardly, thereby opening the tank flush valve. As the seatcontinues its upward movement the nose 18 will pass fromengagement withthe dog 28 by reason of the arcuate, downward path traveled by saidnose; and,""when the seat returns to its normal position, the nose 18will, in its upward-journey, engage the lower face of the dog 28' andcause the some to swivel about its pivot, thereby permitting the nose toeasily understood. en the water in the flush tanlris exhausted, theweight of the valve therein will raise'the weight 25 hack to itsoriginal position.

While I have herein disclosed the pre-' ferred mode of practising myinvention, ll desire it understood that l may make such changes andalterations as would suggest themselves to those skilled in the art andpermitted under the doctrine of mechanical equivalents. a 7
